Structure of new ARSF Database

Things to change in database revision 2

• Move project_flights.area to flights.area ?
• Move project_flights.priority to flights.priority ?
• Remove sensor_status.id primary key and use the submit_time as primary key.

The database is made up of 9 tables, joined together by relations. See below for a diagram of the database tables and relations

The PI table is made up of the PI's name, address and their email address. The table has and internal field called 'id' which is filled in automatically and is referred to whenever a PI is linked to a project code. If you try and delete a PI, and that PI still has project_codes referring to the PI then the Database will prevent you deleting the PI.

pi Table
Key	Field Name	Value Type	Constraints	Notes
Primary Key	id	Integer(4 Bytes)	Required	Value is automatically generated.
	pi_name	Text (variable length)	Required
	address	Text (variable length)		Not required as may not be known at time of entry.
	email	Text (variable length)		Not required as may not be known at time of entry.

The projects table contains all the project codes and what PI relates to which project code. Many project codes can relate to one PI.

projects Table
Key	Field Name	Value Type	Constraints	Notes
Primary Key	project_code	Text (variable length)	Required
Foreign Key	pi_id	Integer(4 Bytes)	Required	The PI's ID from the pi table.
	summary	Text (variable length)
	eufar_code	Text (variable length)
	objective	Text (variable length)

The flights table contains the information about one flight. So if two flights were made in one day, then there would be two entries in the flight table.

flights Table
Key	Field Name	Value Type	Constraints	Notes
Primary Key	flight_id	Integer(4 Bytes)	Required	Value is automatically generated.
	flight_date	Date	Required	The date that the flight took place
	primary_ticket	Integer(2 Bytes)	Required	Primary ticket id for trac
	kml_file_location	Text (variable length)
	data_location	Text (variable length)
	sortie	Text (variable length)	Required	The letter to differentiate multiple flights flown on one day
	notes	Text (variable length)
	secondary_tickets	Integer(2 Bytes) Array
	data_recieved_on	Date

The project_flights table (in database terms prevents a many-to-many relationship) holds data which allows for a single flight to have more than one project code, the table also contains the priorities for the different project codes and the area that was investigated.

project_flights Table
Key	Field Name	Value Type	Constraints	Notes
Primary Key	flight_id	Integer(4 Bytes)	Required	Value must be in the flights table.
Primary Key	project_code	Text (variable length)	Required	Value must be in the projects table.
	priority	Text (variable length)	Required	Value must be in the priorities table.
	area	Text (variable length)	Required

Structure of old ARSF ID-Key-Value database

For furture maintenance.

Indented sublevels mean the child has an "id" field matching the "value" field of the parent. 
If items are on the same level without a separating space, it means they share the same id. 
The flight_* items appear in separate groups, hence the abbreviation.

There is a 39th "kml_link" key but this only appears once, so I think it was replaced by flight_kmlweblink but not deleted. 

Adding a new sensor

To add a new sensor to the status page all you need to do is to add two entries to the database:

ID	Type	Value
f855984c-b5d2-11e3-a2a4-1803732ee31c	sensor_name	Fenix
f855984c-b5d2-11e3-a2a4-1803732ee31c	sensor_type	Hyperspectral

The IDs can be anything but they must match.
